Krobia xinguensis Kullander, 2012
18-Feb.-2012 — A new species of Krobia has been described
Von Thomas Andersen
A new paper by Sven Kullander published in the recent issue of Zootaxa formally describe Krobia xinguensis from localities in the headwaters and in the lower part of the rio Xingu. It is distinguished primarily by a deeper caudal peduncle, and details of its color pattern, including contrasting interorbital stripes and a small dark spot anteriorly on each side of the lower jaw, and a rich orange coloration in live specimens. Krobia xinguensis has previously been known as Krobia sp. "xingu" in the aquarium hobby. In the paper Kullander also state that K. potaroensis and K. paloemeuensis, currently assigned to Krobia, is better included in the catch-all genus Aequidens, until further morphological analyses may provide support for an alternative generic classification of these two species.
